Abstract
Fremgangsmåte for ekstraksjonsrensing av minst en substans som skal isoleres fra et flytende medium, omfattende trinnene med tilsetning til det flytende medium av en damp-avdrivbar organisk forbindelse med et Lewis-type syre-base molekyl hvor minst et N, O og/eller S-atom danner et eller flere aktive steder utstyrt med et fritt elektronpar i resonans med minst et annet par på molekylet, idet den nevnte forbindelse tilsettes i en tilstrekkelig mengde for å fremstille et reaksjonsprodukt fra en likevektsreaksjon mellom den organiske forbindelse og den eller de nevnte substanser som skal isoleres, og med presipitering av likevektsreaksjons- produktet, filtrering av presipitatet, damp-avdrivning av den organiske forbindelse derfra og samling av substansen som skal isoleres i en renset form.A process for extraction purification of at least one substance to be isolated from a liquid medium, comprising the steps of adding to the liquid medium a vapor-stripper organic compound with a Lewis-type acid-base molecule wherein at least one N, O and / or S atom forms one or more active sites equipped with a free electron pair in resonance with at least one other pair of the molecule, said compound being added in a sufficient amount to produce a reaction product from an equilibrium reaction between said organic compound or substance (s). is to be isolated, and by precipitation of the equilibrium reaction product, filtration of the precipitate, vapor evaporation of the organic compound therefrom, and collection of the substance to be isolated in a purified form.
